  • System and method of charging a buffer capacitor
    Patent number: 10862472
    Abstract: In accordance with an embodiment, a method includes monitoring a first voltage across a buffer capacitor; activating a first current path between a power supply node and the buffer capacitor when the monitored first voltage is below a first threshold voltage, activating a second current path between the power supply node and the buffer capacitor when the monitored first voltage is below a second threshold voltage, and transferring power from the buffer capacitor to a driver circuit coupled across the buffer capacitor.

  • Peak current control for a power switch of a power converter
    Patent number: 10530255
    Abstract: Control circuitry for controlling the duty cycle of a magnetizing switch of a power converter containing a demagnetizing switch is described. The magnetizing switch and the demagnetizing switch are switched on within a sequence of commutation cycles in a mutually exclusive manner. The control circuitry is configured, within a commutation cycle from the sequence of commutation cycles, to determine a sensed current signal indicative of a current through the magnetizing switch. The control circuitry determines a ramp signal by adding a slope compensation signal to the sensed current signal. The control circuitry determines a threshold signal and determines a duty cycle for the magnetizing switch for the commutation cycle by comparing the ramp signal with the threshold signal. The threshold signal and/or the slope compensation signal depend on the duty cycle for the magnetizing switch of a preceding commutation cycle from the sequence of commutation cycles.
